CANE CUTTER Filed Apfil 17, 1928 2 Sheets-Sheet 2 Anorn e Patented Apr. 29, 1930 OFFICE IMASAICHISASAKI, OF LII'IUE, TERRITORY OF HAWAII CANE CUTTER Application filed. April 17,

The present invention relates to an attachment for cutting sugar canes and has for its prime object to provide a construction for utilization in' conjunction with the cane cutter .5 disclosed in my pending application Serial N 0. 249,659 filed January 26, 1928.

Another very important object of the invention resides in the provision of an attachment of this nature which is reliable and eflicient for cutting crawling sugar canes.

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings: Figure l is a top plan view of a machine embodying the features of my invention,

Figure 2 is a side elevation of one of the endless cutters, Figure3 is a detail elevation of one of the cutting mechanisms for standing cane, portions being shown in section, and

Figure 4 is a detail view of the rear end of one of the rockable bars. 7 7

Referring to the drawings in detail it will be seen that the letter G denotes generally a tractor of any preferred or conventional con- 30 struction such for example as the well known Fordson tractor. A frame F of suitable formation is secured to the tractor and has journaled therein a shaft 5 extending transversely of the tractor and operatively connected to 35 a power takeoff 6 usually-provided on such tractors by means of a suitable chain and sprocket mechanism 7.

Exte'nsions8-are disposed to the side of the frame F projecting laterally therefrom and support brackets -9. Geancasings 10 have non-circular extensions 11 projecting therefrom and slidably-received in the brackets 9. Hollow elongated arms 12 project forwardly from the gear casing 10 and support hingedly on their forward ends auxiliary arms 24 operatively connected by suitable means 25 for rocking the auxiliary arms.

Cutting mechanism 26 is mounted on these arms at their lower ends. All the structure 56 thus far defined has been disclosed in detail 1928. Serial No. 270,782.

inmy co-pending application and has been illustrated herein merely for the purposes of bringing out the utility of the attachment.v

Referring now to the attachment it will be seen that frame members 30 attached to the tractor and extending forwardly to the sides thereof support the transverse bar 31 adjacent their forward ends and a transverse shaft 32. V

The shaft 32 is journaled in bearings 33. A plurality of pairs of bars 34 have bearings 35 to rotatably receive the shaft 32 and their rear ends are provided with arcuate loop members 36 to receive the bar 31, as indicated in Figure 4. The forward'ends of these bars 34 of each pair are twisted and bent inwardly toward each other and merge into spaced parallel extensions 37 between the forward ends of which is journaled a sprocket on the axle 38 of wheels 39. An endless chain 40 is trained oversprockets 41 and 42 the former being fixed to the shaft 32 and the latter rotatable on the axle 38 and this chain has at spaced intervals knives 44 projecting out wardly therefrom.

Frames 45 are mounted'on one of the extensions 37 of each pair and have-journaled therein saws46 the shafts 47 of which have pinions 48 meshing with combinedsprccket and gears 49, the sprocket portions of which are engaged with the upper run of the chain 40. The shaft 32 is operatively connected to the shaft 5 by means of the chain and sprocket mechanism 15. H g

It-will therefore be seen that'when the mechanisms 26 are in operation my attachment mechanism is also in' operation and the chains will move knives-4O and cause the rotation of the saws so as tose'ver crawling cane on theground. I n

It is thought that the construction; utility and advantages of this invention will fnowbe quite apparent to those-skilled in this "art without a more detailed description thereof. The'pres'ent embodiment of the invention has 95 been disclosed in detail merely'by "way of example since in actual practice it attains the features of advantage"enumerated as "desir f able'inthesta-tement of theinvention andthe above description.- i
